Abstract
The present invention relates to a powder for sintering containing a mixture of a metal powder and metal oxide particles having an average particle diameter of 5 nm or more and 200 nm or less, and to a sintered body.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A powder for sintering comprising a mixture comprising:
a metal powder and metal oxide particles having an average particle diameter of 5 nm or more and 200 nm or less.
2 . The powder for sintering according to claim 1 ,
wherein the metal oxide particles comprise at least one metal oxide selected from the group consisting of Al 2 O 3 , MgO, ZrO 2 , Y 2 O 3 , CaO, SiO 2 , and TiO 2 , as a main component.
3 . The powder for sintering according to claim 1 ,
wherein the metal oxide particles is added in an amount of 0.03% by mass or more and 0.7% by mass or less in the powder for sintering.
4 . The powder for sintering according to claim 1 ,
wherein the metal oxide particles is made of a single metal oxide having a purity of 90% by mass or higher.
5 . A sintered body obtained by sintering a compact of the powder for sintering as described in claim 1 .Join the waitlist — get patent alerts
